As promised I built a dual band satellite antenna that will work with an inexpensive FM HT for making satellite mediated QSOs. There are not many materials needed and only a couple of things you can’t get at your local hardware store. The link to the original post about this moxon/yagi is below alone with some photos and information about my implementation.

I used a couple of pre-cut 1/2” PVC pieces, a PVC coupler (just friction fit, no glue needed), some 8 AWG grounding wire and some electrical tape.

Antenna materials

Drilling holes

70cm Yagi complete

I cut all the pieces to size and drilled holes through the PVC for them. I used electrical tape near the holes to keep the pieces mostly centered. I bent the moxon pieces by eye. I used small wooden dowel to space the moxon pieces and then electrical taped them.

Measuring spacers

Spacer and moxon elements

Attaching spacers

The most difficult part was soldering the coax to the feed point as #8 solid copper is a big heat sink. I ended up using a torch and pipe solder but if I were building it again I’d probably use bolts with a couple of large washers to create screw terminals. You could order some larger screw terminals from Amazon, etc. and use those instead and it would likely work better.

Coax coil choke

The only part I needed to order from Amazon was the RG-58 and BNC crimp ends as I was out. If you are not sure how to crimp ends you can buy a pre-crimped patch cable with the correct connectors for your HT and just cut one of them off. I made mine about 2m long so I’d have enough to hang the HT on my belt. After you connect the cable to the feed point, wrap it around the PVC 4 or 5 times and tape it off…I used small zip ties I had for a stronger connection and also zip tied the coax a couple of other places for additional mechanical stability.
